3 - Auto Brake
The automatic brake function is activated last.
If in this situation the driver has not yet started to
take evasive action and the risk of collision is
imminent then the automatic braking function is
deployed - this takes place irrespective of
whether or not the driver brakes. Braking then
takes place with full brake force in order to
reduce collision speed, or with limited brake force
if it is sufficient to avoid a collision.
The seatbelt tensioner can be activated in con-
nection with the engagement of the automatic
brake function.
In some situations, the action of Auto-brake may
begin with light braking and then progress to full
brake action.
When City Safety has prevented a collision with a
stationary object, the car remains stationary in
anticipation of positive action by the driver. If the
car has been braked to avoid collision with a
slower vehicle in front, its speed is reduced to
match that of the vehicle in front.
NOTE
On cars with manual gearbox, the engine
stops when the Auto-brake function has stop-
ped the car, unless the driver has managed to
depress the clutch pedal beforehand.
The driver can always interrupt a braking inter-
vention by firmly depressing the accelerator
pedal.
NOTE
When City Safety brakes, the brake lights
come on.
When City Safety is activated and brakes the
vehicle, the driver display shows a text message
to the effect that the function is/has been active.
WARNING
City Safety must not be used by the driver to
change his/her driving style - the driver must
not rely on City Safety alone and allow it to do
the braking.

Setting the warning distance for City
Safety
City Safety is always activated but the driver can
select the warning distance for the function.
NOTE
The City Safety function cannot be deacti-
vated. It is activated automatically when the
engine/electric operation is started and
remains switched on until the engine/electric
operation is switched off.
The warning distance determines the sensitivity
of the system and regulates the distance at
which a visual, acoustic and brake pulse warning
should be deployed.
To select warning distance:
1. Select Settings My Car IntelliSafe in
the centre display's top view.
2. Under City Safety Warning , select Late ,
Normal or Early to set the desired warning
distance.
If the
Early
setting produces too many warnings,
which could be perceived as irritating in certain
situations, the
Normal
or
Late
warning distance
can be selected.
When warnings are perceived as being too fre-
quent or disturbing, the warning distance can be
reduced, which reduces the total number of
